Yamaha A-S 1000 & 2000 --- How Good?

Totally NOT in agreement with Pubul57.

No contest with the Yamaha 2000 series.

Circuit topology, parts quality, assembly quality and surface conductvity of signal route is nearly on-par with Accuphase.

The AS2000 cannot be compared with an AX-596. The 596 is a good amp for the money. The AS2000 is in another league altogether.

Unfortunately, the AS2000 has been removed from Yamaha's 2012 catalogue. The snobby nature of our hobby makes it hard to support this product when one can purchase a Simaudio Moon amp for less money. And that's a shame. This Yammy betters most of the competition at this price level on sound, (including the Sim) smokes them on features, and is STILL built to last 30 years - something that cannot be said of many flimsy boutique amps out there.

No that there aren't any left at dealers - I think it will become a classic in due time.

How do the A-S1000 and A-S2000 differ? The power output for these two amps is the same.

I don't there is a difference, what I caution is against hyperbole which makes minor difference seem monumental. I've seen seasoned audiophile who could not consistent determine if a 30 watt tube amp or a 200 watt SS amp was playing - no two amps could be more different, and yet. Not saying the AS-2000 is not a better amp, but I find claims that one piece will blow away another piece is almost always, well. overblown. It is a beautiful amp though and worth having on those grounds alone assume decent performance, which reviewers seem to agree is pretty darn good - I just would not expect transformations from night to day.

I understand there are some differences under the hood - but mostly, the AS2000 is a touch more refined and transparent. Now it all depends how much of that ''touch'' you feel might make a difference. I could definitely hear the 2000 having an edge over the 1000. It is subjective of course, but I found the 1000 to less involving. Still the 1000 is a very good machine and a good buy nevertheless. I did my auditioning with some very revealing speakers, and the 2000 was my favorite. If you can spring it, the 2000 is the way to go.

The audible differences are less pronounced between the cd players (1000 and 2000) however, as I could not detect anything difference worth mentioning. They are both equally impressive with that silky-smooth transport.

"The audible differences are less pronounced between the cd players (1000 and 2000) however, as I could not detect anything difference worth mentioning." It is interesting how often I find this to be the case with CD players by any given manufacturer - pro reviewers have been saying much the same thing as well with these two Yamaha CD players.
